Compressor /casscade/ fill station ???'s

i am inputting the request tonight, and see that they have listed " complete air-fill system" that was listed under the "basic heading". And under the speacialized heading was the " compressor/casscade/fill station". I am asking for funds for a compressor/casscade/fill station, and want to check the right box. I think that I will list it under the specialized heading, what do you think.

Also for those who were funded in years past for a similar project, what amount did you ask for and what did you recieve.
